Description

Die Erfindung betrifft einen Hydraulikmotor bzw. eine Hydraulikpumpe, gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a hydraulic motor or a hydraulic pump, according to the preamble of claim 1.

Flügelzellenpumpen bzw., -motore mit zentrischer Lagerung des innenliegenden Rotors in stillstehenden Gehäusen mit sichelförmigen und konstanten Förderquerschnitten sind bekannt. DE 41 15 642 C2 beschreibt einen Hydraulikmotor bzw. Pumpe letzter Bauart. Aus der DE PS 158 549 ist ein Drehkolbenmotor bekannt, dessen Käfigring aus in einer Nut geführten Gleitschuhen, die über Stifte mit den Schiebern verbunden sind, besteht. Die Gleitschuhe laufen mit den Schiebern um den Exzenter der stehenden Achse.Vane pumps or motors with central bearing of the inside Rotors in stationary housings with sickle-shaped and constant Conveying cross sections are known. DE 41 15 642 C2 describes one Hydraulic motor or pump of the latest type. From DE PS 158 549 is a Rotary piston engine known, the cage ring made of guided in a groove Slide shoes, which are connected to the sliders by pins. The Sliding shoes run with the sliders around the eccentric of the standing axis.

Aufgabe der Erfindung ist es in einfacher Bauweise die Nabe eines Rades oder eine Walze selbst zum Rotor des Flügelzellensystems zu machen und die Schieber vom Stillstand an im hydraulischen Kraftschluß an der Achse zu halten. Dieses Ziel wird erfindungsgemäß mit den Merkmalen des kennzeichnenden Teils des Patentanspruches 1 erreicht.The object of the invention is the simple construction of the hub of a wheel or to make a roller itself the rotor of the vane system and the To hold the slide in the hydraulic adhesion on the axis from standstill. This aim is achieved according to the invention with the characteristics of the Part of claim 1 reached.

Die Käfigringe eliminieren den Nachteil von Flügelzellenpumpen/Motoren, deren Förderung erst einsetzt, nachdem die Schieber infolge der radialen Auslenkung durch die Fliehkraft die Zellen mit geringen Spalten schließen d. h., bei Mindestdrehzahl.The cage rings eliminate the disadvantage of vane pumps / motors, their Funding only begins after the slide due to the radial deflection due to the centrifugal force the cells close with small gaps d. i.e. at Minimum speed.

Die Erfindung ist anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.The invention is based on one shown in the drawing Embodiment explained in more detail.

Es zeigen:Show it:

Fig. 1 eine Seitenansicht des Flügelzellenmotors/Pumpe im Schnitt, Fig. 1 is a side view of the vane motor / pump in section,

Fig. 2 Schnitt A-B quer zur Flügelzellenachse, Fig. 2 section AB transverse to the vane axis,

Fig. 3 Schnitt C-D quer zur Flügelzellenachse. Fig. 3 section CD transverse to the vane axis.

Eine symmetrische Nabe 1 eines Rades oder eine Walze 1 ist drehbar, zentrisch auf der stillstehenden Achse 2 gelagert.A symmetrical hub 1 of a wheel or a roller 1 is rotatable, mounted centrally on the stationary axis 2 .

Die Nabe 1 ist zwischen den nach innen abgedichteten Lagerungen 3 in der Bohrung kleiner gehalten und hat in den inneren Stirnflächen 12 hinter den Dichtringen 4 zylindrische Ringräume, in die die exzentrischen Käfigringe 5 eintauchen. Die Nabe 1 hat längs zur Achse parallele radiale Schlitze 6 ausgehend von der Innenbohrung. The hub 1 is kept smaller in the bore between the inwardly sealed bearings 3 and has 4 cylindrical annular spaces in the inner end faces 12 behind the sealing rings, into which the eccentric cage rings 5 are immersed. The hub 1 has radial slots 6 parallel to the axis, starting from the inner bore.

In den Schlitzen 6 arbeiten die Schieber 7 mit seitlichem Gleitspiel dreiachsig beweglich. Der sichelförmige Förderquerschnitt 8 wird dadurch gebildet, daß die Achse 2 innerhalb der Schieberlänge exzentrisch versetzt ist.In the slots 6 , the slides 7 work with three-sided movable sliding play. The crescent-shaped conveying cross section 8 is formed in that the axis 2 is offset eccentrically within the slide length.

Der maximale Flüssigkeitsquerschnitt liegt der Exzenterachse 9 gegenüber und ist doppelt so dick, wie die Exzentrizität. Dichtringe sitzen fest auf den zylindrischen Teilen der Achse 2 und begrenzen den Flüssigkeitsraum 8.The maximum liquid cross section lies opposite the eccentric axis 9 and is twice as thick as the eccentricity. Sealing rings are firmly seated on the cylindrical parts of the axis 2 and delimit the liquid space 8 .

Die Käfigringe 5 haben als Mittelachse die Exzenterachse 9 und halten dadurch die Schieber 7 im ständigen Eingriff. Die zentrifugale Anlagekraft steigt mit der Drehzahl.The cage rings 5 have the eccentric axis 9 as the central axis and thereby keep the slider 7 in constant engagement. The centrifugal force increases with the speed.

Die Zuführung 10 und Abführung 11 der Flüssigkeit erfolgt jeweils im Zentrum der Achse 2. Die Schieber können rechteckig mit Linienberührung sein, siehe Fig. 2, konkav oder konvex an den Dichtleisten.The liquid 10 is supplied and discharged 11 in the center of the axis 2 . The slides can be rectangular with line contact, see Fig. 2, concave or convex on the sealing strips.

Zylindrische Schieber, siehe Fig. 3, rollen gegen die stillstehenden Flächen. Zusätzlich kann der Käfigring mit einem innenliegenden Laufring gefüttert sein. Dadurch kann das wirksame radiale Gesamtspiel, das einen wesentlichen Teil der Spaltverluste bestimmt, verringert werden.Cylindrical slides, see Fig. 3, roll against the stationary surfaces. In addition, the cage ring can be lined with an inner race. As a result, the effective total radial play, which determines a substantial part of the gap losses, can be reduced.

Die Dichtringe können ausgeführt sein mit federbewehrten Gleitringdichtungen und mit zusätzlichen Flüssigkeitskammern.The sealing rings can be designed with spring-loaded mechanical seals and with additional liquid chambers.
